3.6.1
The 17-bit x 17-bit multiplier is capable of signed or
unsigned operation and can multiplex its output using a
scaler to support either 1.31 fractional (Q31) or 32-bit
integer results. Unsigned operands are zero-extended
into the 17th bit of the multiplier input value. Signed
operands are sign-extended into the 17th bit of the
multiplier input value. The output of the 17-bit x 17-bit
multiplier/scaler is a 33-bit value that is sign-extended
to 40 bits. Integer data is inherently represented as a
signed 2’s complement value, where the Most
Significant bit (MSb) is defined as a sign bit. The range
of an N-bit 2’s complement integer is -2
• For a 16-bit integer, the data range is -32768
• For a 32-bit integer, the data range is
When the multiplier is configured for fractional multipli-
cation, the data is represented as a 2’s complement
fraction, where the MSb is defined as a sign bit and the
radix point is implied to lie just after the sign bit (QX
format). The range of an N-bit 2’s complement fraction
with this implied radix point is -1.0 to (1 - 2
16-bit fraction, the Q15 data range is -1.0 (0x8000) to
0.999969482 (0x7FFF) including 0 and has a precision
of 3.01518x10
ply operation generates a 1.31 product that has a pre-
cision of 4.65661 x 10
The same multiplier is used to support the MCU multi-
ply instructions, which include integer 16-bit signed,
unsigned and mixed sign multiply operations.
The MUL instruction can be directed to use byte or
word-sized operands. Byte operands will direct a 16-bit
result, and word operands will direct a 32-bit result to
the specified register(s) in the W array.

The adder/subtracter is a 40-bit adder with an optional
zero input into one side, and either true or complement
data into the other input.
• In the case of addition, the Carry/Borrow input is
• In the case of subtraction, the Carry/Borrow input
The adder/subtracter generates Overflow Status bits,
SA/SB and OA/OB, which are latched and reflected in
the STATUS register:
• Overflow from bit 39: this is a catastrophic
• Overflow into guard bits 32 through 39: this is a
The adder has an additional saturation block that
controls accumulator data saturation, if selected. It
uses the result of the adder, the Overflow Status bits
described
(CORCON<7:6>) and ACCSAT (CORCON<4>) mode
control bits to determine when and to what value to
saturate.
Six STATUS register bits support saturation and
overflow:
• OA: ACCA overflowed into guard bits
• OB: ACCB overflowed into guard bits
• SA: ACCA saturated (bit 31 overflow and
• SB: ACCB saturated (bit 31 overflow and
• OAB: Logical OR of OA and OB
• SAB: Logical OR of SA and SB
The OA and OB bits are modified each time data
passes through the adder/subtracter. When set, they
indicate that the most recent operation has overflowed
into the accumulator guard bits (bits 32 through 39).
The OA and OB bits can also optionally generate an
